FABRIC-CLAMP FOB UMBRELLAS.

Specification of Letters Patent.

Application filed November 10, 1910.

Patented Apr. 11, 1911. Serial No. 591,711.

To all whom it may concern:

Be it known that we, CHARLES RABER and GEORGE GUNDLAOH, citizens of theUnited States, residing at Brooklyn, city and State of New York, haveinvented certain new and useful Improvements in Fabric-Clamps forUmbrellas, of which the following is a clear, full, and exactdescription.

The object of this invention is to provide a clamp for securing thefabric at the apex of an umbrella to the rod in order to provide aneater, more compact and more attractive fastening, to reduce the costof the same, and to do away with stitching the fabric in place as iscommonly done today.

In carrying out our invention, we provide a pair of dish or cup shapedferrules or disks, one adapted to fit within the other, the outerpreferably provided with a turnedover rim in order to prevent tear orwear on the cloth. Between these two ferrules we locate the fabric ofthe umbrella at the apex, clamping the same tightly between the twoferrules by upsetting the hub of the inner dish-shaped ferrule over theouter ferrule. These two ferrules are then forced by pressure over therod of the umbrella, where they may be fastened in any manner known tothe art. We prefer that they be wedged in place and held by the adhesionof the metal of the inner ferrule against the umbrella rod.

The scope of our invention will be pointed out in the claim.

In the accompanying drawing, Figure 1 is a transverse central section ofa part of an umbrella showing the application of our improved inventionthereto. Fig. 2 is a view of the outer ferrule in section, below whichis shown the cloth, and immediately below which is shown the innerferrule all in section before being secured one to the other. Fig. 3 isa view of our device in side elevation, as applied to an umbrella, onlypart of the umbrella being shown in such View.

As shown in the accompanying drawing, we provide a dish-shaped ferrule2, preferably having an ornamental outer surface, and having its lowerrim 3 turned over to produce a rounded edge. We provide an inner ferrule6 having a flanged skirt and a hub portion 5. The fabric 7 is placed inposition between the two ferrules, and the hub 5 of the inner ferruleforced through the apex of the fabric, so that the skirt of the innerferrule will pull the fabric into the dish-shaped recess of the outerferrule, and hold it in place. We then upset that part of the hubextending through the outer ferrule, so as to make a permanent clampupon the fabric. This ferrule 6 is turned over as indicated at 9 in thedrawing. We then insert the whole over the end of the umbrella rod 1,which should be of greater diameter than the interior of the hub, and byproper mechanism force the same down in the desired position on the rod.As the fabric is fast to the clamp thus formed, and as the outer end ofthe fabric in the umbrella is fast to the rib 8, pull on the ferruletends at all times to hold it in place in addition to its adhesive gripupon the rod.

e claim as our invention:

The herein described fabric holding clamp for umbrellas and the like,consisting of the umbrella rod, its ribs, its fabric covering, saidfabric covering having a circular opening through which the rodprotrudes, an inner ferrule having a hub and a flared skirt at the lowerend of the hub, the hub adapted to be passed through the fabric, anouter ferrule of greater diameter than the inner ferrule, having flaredsides and a contracted neck, the lower ends of the flared sides havingthe metal thereof overturned inwardly and resting below the lower edgeof the inner ferrule, the hub of the inner ferrule being turned over andforced down upon the outer ferrule at its restricted orifice to firmlyclamp the fabric therebetween, substantially as shown and described.

Signed at New York city, New York, this 9th day of November 1910.
